Способ выделения благородных металлов из растворов, включающий химическое осаждение благородных металлов в виде нерастворимых осадков, отделение осадков и последующую переработку полученных осадков известными способами, отличающийся тем, что, с целью максимального (> 99,8%) извлечения благородных металлов проводится одновременное совместное осаждение их осадительной смесью из хлоридов и сульфидов щелочных металлов, причем количество подаваемого в смеси хлорида щелочного металла рассчитывается на 100% осаждения серебра, а количество сульфида щелочного металла должно составлять не менее 450% от теоретически необходимого для осаждения благородных металлов (Pt, Рd и т.д.) в виде сульфидов.A method for separating precious metals from solutions, including chemical precipitation of precious metals in the form of insoluble precipitates, separating the precipitates and subsequent processing of the obtained precipitates by known methods, characterized in that, in order to maximize (> 99.8%) recovery of the noble metals, they are simultaneously co-precipitated precipitation mixture of chlorides and sulfides of alkali metals, and the amount of alkali metal chloride supplied in the mixture is calculated on 100% deposition of silver, and the amount of sul Alkali metal fide should be at least 450% of theoretically necessary for the deposition of noble metals (Pt, Pd, etc.) in the form of sulfides.
